From 0cf76ccb4736473a958d9fd36ed914e2d25d594a Mon Sep 17 00:00:00 2001 From: ArthurHoaro Date: Wed, 21 Oct 2020 13:12:15 +0200 Subject: Feature: add a Server administration page It contains mostly read only information about the current Shaarli instance, PHP version, extensions, file and folder permissions, etc. Also action buttons to clear the cache or sync thumbnails. Part of the content of this page is also displayed on the install page, to check server requirement before installing Shaarli config file.
